Purdue University proposes to assess the structural and mechanical integrity of electron beam (EB) weldments on powder metallurgy with hot isostatic pressing (PM-HIP) manufactured pressure vessel steel under service-relevant irradiation conditions. The objective of the proposed research is to qualify the combination of EB welding and PM-HIP technologies for pressure vessel construction by comparing EB-welded PM-HIP materials to conventional forged components. The experiments will use existing equipment at partner locations (INL and Westinghouse) to irradiate the samples and evaluate material properties.
